hey, SAM ROCKHARD, sorry, somehow i never saw your post where you say that you live in canada...
i don't know off hand really where you might get the same thing up there. i think that Tractor Supply might have just repackaged a generic airfilter.
i have my carb all taken apart right now 'cause its gonna be raining here for a few days, so i could measure the inside diameter of the filter and let you know what it is. you could probably find the same thing in an auto parts store.
